Filed Maps and Corner Record Search

You can search for Napa County maps filed with the County Recorder by title, date filed, map data (map type, book number, page number), by map number or by location. If you are unable to locate a filed map record online, please contact the Recorder for assistance at recorder-clerk@countyofnapa.org or (707) 253-4105.

Alternatively you can search for a Napa County Corner Record by number or location. Corner Records facilitate the perpetuation of monuments originally shown on previously recorded maps. Corner Records are filed and indexed by the County Surveyor. If you are unable to locate a corner record online or have any other questions regarding these documents, please contact the County Surveyor at publicworks@countyofnapa.org or (707) 253-4351.
